Application filed May 31. 1907- Serial No. 376.558.

To all whom it may concern:

Be it known that I, PETER J. WlcKBLoM, a citizen of the United States,residing at Bishop llill, in the county of Henry and State of lllinois,have inventeda new and useful Centrifugal Pump, of which the followingis a specification.

This invention relates to centrifugal pumps of that general classespecially designed for irrigating or flooding rice fields and otherlands.

The object of the invention is to provide a comparatively simple andthoroughly ellicient pump in which the water is elevated from a well orother source of supply and discharged into a suitable receiving tankwithout the employment of pistons, actuating rods and similar operatingdevices.

A further object of the invention is to provide a pump including arotary casing having a tubular member secured thereto and communicatingwith the inlet pipe thereby to discharge the water into the receivingtank when the casing is rotated.

A further object is to provide a valve for controlling the discharge ofwater from the tubular member, said valve being movable to open positionby centrifugal force when the casing is rotated.

A still further object of the invention is to generally improve thisclass of devices so as to increase their utility, durability andetliciency. i

Further objects and advantages will appear in the following description,it being understood that. various changes in form, proportions and minordetails of construction may be resortedV to Within the scope of theappended claims.

1n the accompanying drawings forming a part of this specification:Figure 1 is a side elevation partly in section of a centrifugal pumpconstructed in accordance With my invention. Fig. 2 is a top plan viewof a portion of the same. Fig. 3 is a longitudinal sectional view partlyin side elevation of the casing and tubular member. Fig. 4 is a sideelevation partly in section of a modified form of pump. Fig. 5 is atransverse'sectional view taken on` the line 5 5 of Fig. 4.

Similar numerals of reference indicate cord rawings.

The improved pump forming the subject matter of the present inventionincludes a fluid conducting pipe 5, one end of which is responding partsin all .of the gures of theextended to the bottom of la well orothersource of liquid supply 6, while the opposite end thereof extendsthrough the bottom of a receiving tank or vessel 7.

Mounted for rotation on the upper end of the pipe 5 is a casing 8 havingits lower end provided with a depending sleeve or collar S) whichengages an annular flange or rib 10 extending laterally from theexterior walls of the pipe 5, thereby to form a bearing for the casing.The interior walls of the casing o' are formed with an annular groove 11for the reception of a packing ring 12 which serves to form an air andWater tight joint between the casing and pipe.

The lower end of the pipe 5 is provided with a casing or chamber 13having an opening 14 formed therein and normally closed by a llap valvel5 which serves to control the flow of Water from the well 6 through thepipe to the casing.

The upper end of the pipe 5 short distance Within the casing S andsecured to the free end of said pipe is a flap valve 16 for the purposehereinafter referred to.

Extending laterally from the exterior walls of the casing S is a nipple17 the exterior walls of which are inclined for engagement with atubular member 18, the latter being prefer# ably extended at rightangles to the casing S and having its rear end open so as to form asource of communication between the pipe and tube. Secured to the outeror free end of the tubular member 18 is a depending bracket or yoke 19which forms a support for a transverse pin or shaft 20. One end of theshaft 2O is extended laterally beyond the bracket 19 to form a bearingfor the intermediate portion of a valve supporting member. The valvesupporting member consists of a pair of diverging arms 21 and 22 havingan eye 23 formed at the juncture thereof for the reception of the shaftor pin, whereby the valve supporting member 1s free to oscillate on saidshaft.v Pivotally mounted at 24. on the arm 22 is a valve 25 whichnormally closes the adjacent 4end of the tubular member 18 so as tocontrol the discharge of liquid through the tubular member 18 into thereceiving tank 7. The free end of the arm 21 is provided with a terminalWeight 26 which serves to normally close the valve 25, the tiltingoroscillating movement of the arm 21 being limited by the stop pin orclosure 27 eX- tending laterally from the bracket 19, as shown.

extends a .i'ltoltedv riveted, or otherwise rigidly' ^Se cured to theupper or free end of the casing 8 is a sleeve 28 provided with aninterior chamber 29 adapted to receive a quantity of water or otherfluid for priming the pump. E am' X forms a chamber for the reception ofthe priming liquid and also constitutes a wheel or.:

pulley l'or rotating the casing.

The exterior walls of the formed with laterally extendingiianges V31which serve to guide Athe belt 30 and'prevent accidental displacement ofthe same, while the interior walls of the' sleeve are formed with aiiange 32 which constitutes a seat for a iiap valve 33.

1n operating the ump the flap valve 33 is elevated and a small)`quantity of Water introduced in the chamber 29 from whence it iowsthrough the valve 33 into the interior of the casiny 8, the valve 16having been reviously closed. The belt is then operate( to-rotate thecasing 8 which causes the tubular member 18 to revolve within the tank7. As the tubular member or arm 18 revolves the valve/25 will be thrownoutwardly by centritugal force to open position thus ermitting theprimingfluid in the casing 8 to ow outwardly throu h the tubular member18 into the tank 7. the i'luidjs/dischargedffrom the tubular member 8the valve 16 will be moved to open position thus creating ay suction inthe lower portion of the pipe 5 which automatically opens the flap valve15 and causes the water to ascend inthe pipe 5 to the casing 8Y fromwhence it is discharged through the Atubular member 18 into thereceiving tank 7. When the tubular' member 18 ceases to rotate theweight 26 will automatically return the valve4 25 to closed position andthus cut. off the flow or' water to the tank 7.

The upper oir/free edge of the tank 7 is preferably curved inwardly, asindicated at 34 so as to prevent the liquid discharged from the tubularmember 18 from splashing over the up er edge of said tank.

t will of course be understood thatv the water in the receiving tank 17may be conducted through a suitable pipe or irrigating ditch to thesource of consumption and that as many tubular members or arms may befrlmed on the casing or head, as found desira e.

The collar 10 bears against a transverse brace 35 spaced from the bottomof the receivin tank 7 which latter is formed with'a suitab e bearingfor the reception of the pipe 5 and serves to sustain the Weight of thecas' ing and its associated parts.

cured together and the pulley 43 may be' pro# vided with aninteriorchamber similar in construction'to the chamber 29 ingFig. 1 of thedrawings so as to permit the introduction of a quantity ofwater forpriming the pumlp.

From the foregoing descrlption it is thoug that the construction andoperation of the device will be readily understood by'those skilled inthek lart and .further description thereof is deemed unnecessar '.f
